Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700904, here are decompositions:

11 + 8700893 = 8700904
71 + 8700833 = 8700904
131 + 8700773 = 8700904
137 + 8700767 = 8700904
383 + 8700521 = 8700904
431 + 8700473 = 8700904
503 + 8700401 = 8700904
521 + 8700383 = 8700904

Showing the first eight; more decompositions exist.
